EVOLVE Portable Column Loudspeaker
Please monitor the PK LED in the FX channels. The indicator should only light up briefly at the
occurrence of high signal peaks. If the indicator is constantly lit, you should lower the send
levels of those channels where the program peaks occur. For further information, please read
the paragraphs about the FX unit.
AUX control
The AUX control is primarily meant for establishing an independent mix, e.g. for monitor or a
second room/zone. The signal routing is always pre VOLUME control.
PK indicator
The peak indicator plays a key role when setting input levels. The PK (peak) LED on the
EVOLVE provides a visual indication of the risk of distortion before you hear it through the
connected speaker systems. The peak indicator checks the signal level pre and post of the
channel's VOLUME control and indicates the maximum of both levels. If the PK LED blinks
frequently or lights continuously, the corresponding channel is likely to start clipping and you
will need to reduce the volume slightly. The peak LED are triggered at a level of -6 dB below
the point of distortion.
If lowering the channel VOLUME is not sufficient to reduce signal peaks, carefully turn the
GAIN control down.
Keeping an eye on the indicator during a performance is also a good idea, because some
changes in the bands dynamics or even a change in keyboard settings can easily lead to
channel clipping, resulting in the degradation of the overall sound.
VOLUME control
The VOLUME control sets the volume of the corresponding channels, resulting in a balanced
mix. The control should be positioned initially at "0", leaving you with enough flexibility to
balance the mix. The overall volume is adjusted through the use of the master controls. Even
though the channel controls offer an additional level of +15 dB, we would like to advise you to
exceed the "8" mark only in very few exceptional cases. If the EVOLVE column speaker's
summing bus gets "overloaded" with too many "high level" input channels, despite its special
gain structure, the summing amplifier could be driven into clipping.
The best signal to noise ratio can be achieved if channel volume and master volume controls
are set in the same range.

FX
FX ON switch (with indicator)
This switch turns the internal FX unit on and the green LED turns on. Please keep in mind that
you can also use an external footswitch for turning the FX unit on or off. In this case, the LED
also shows the actual operational status of the FX unit. If you want to use a footswitch, the FX
ON switch has to be engaged first. The FX unit is activated and you can use the footswitch to
switch the selected effect program on or off.
FX to AUX control
This control allows you to add the FX output signal (pre volume control) to the AUX channel.
PK indicator
This indicates to the user that the internal FX unit is on the verge of clipping, e.g. at a level of
-6 dB below the risk of overdrive. To achieve an adequate signal to noise ratio, please adjust
the FX units' input level as follows:
1.
2.
3.
4.
Electro-Voice
Establish a "dry" mix - without effect settings - refer to the previous instructions.
Position the FX VOLUME control at the "5" mark.
Turn the FX/PARAMETER rotary control to select the desired FX program preset.
Press the FX ON switch.
